USB to RS232 RS485 TTL UART Interface Converter Module

Product description

This adapter module is a high-performance USB to RS232/485/TTL interface converter module. It utilizes the FT232RL chip as its core, supporting USB 2.0 standard and enabling bi-directional data transmission between USB and RS232/485/UART (TTL). The module is characterized by its user-friendly interface, stability, and reliability, making it widely applicable in various industrial electronic devices, suitable for both DIN-rail and screw-fixing installations. Users can utilize these interfaces to communicate with other devices, facilitating the transmission and reception of information. Furthermore, this product supports multiple operating systems, including Windows, Linux, Android, and macOS.

Product Features

• Onboard integrated power isolation, no additional power supply required for the isolated end
• Onboard integrated digital signal isolation, characterized by high reliability, strong anti-interference, and low power consumption
• User-friendly communication interfaces, smooth and robust USB-B and RS232 interfaces, RS485 and UART (TTL) utilizing standard 5.08mm pitch pluggable terminal blocks
• Onboard TVS (Transient Voltage Suppression) diodes effectively suppress surge voltage and transient spikes in the circuit, providing lightning and electrostatic protection
• The module supports multiple operating systems and development platforms, including Windows, macOS, Linux, and Android.
• Onboard power, TXD, RXD, and VCCIO (TTL logic level) indicators for status indication
• Onboard UART (TTL) level switching switch, enabling convenient and quick switching between 3.3V and 5V
• 120-ohm switching switch for the RS485 interface, allowing convenient and quick switching
• Designed for DIN-rail installation as well as screw-fixed structures, catering to a wider range of application scenarios.
